Included in the OR50 program was a selection of social activities. I chose the walking tour of the City of York. The core of the city is ringed by walls dating back to Roman times. I doubt that original wall were constructed sufficiently wide to permit today’s normal automobile traffic.

The bus dropped us off near the Yorkshire Gardens, and we walked towards the town centre, along the inside of the wall.

We started our walking tour by the lawn by the wall.

Just before crossing the Lendal Bridge, we could look down onto the road beside the riverside.

The passing centuries inside the city walls have allowed the maturity of urban forestry.

Beyond the narrow entry gate is a walled courtyard. Holy Trinity Church dates back to the 12th century.

In the 17th and 18th century, the pews were partitioned into small compartments that families would share on days of worship. Slipping in or out of a sermon would be unlikely, with latches on the doors.

The wealthy might get compartments a little farther from the pulpit, but the poor would sit close under the view of the minister.

Farther back in the church is the altar, under a stained glass window. There were some descriptions about the history and renovations planned for the church, displayed on easels.

Coming out of the shopping district, one of the lanes leads to York Minster.

York Minster is one of the largest cathedrals in Europe, and nearly impossible to photograph with the widest of lenses. Here’s the view west that includes the tower.

Outside the Minster is a bronze of Constantine I, who ruled Britannia under the Roman Empire from York in the first century.

As we walked around the east end of the Minster, we found stonework in preparation for installation in the renovation.

Some of the more complicated pieces had been deconstructed and numbered for later reassembly.
